IMPRQVBMBT IN STOPPERS FOR JARS AND BOTTLES.

The Schedule referred to in these Letters Patent and making part of thesame I, HENRY \V.'KETCHAM, ofthe city, county, and

being shown in section.

Figure 2 shows the ring in plan vieu.k

Figure 3 represents the stopper as applied in seal.- inga jar or bottle,the latter with the packing-ring shown in section.

The. stopper A is p1 eferably constructed of glass, but any othersuitable material may be used.

The conical portion a and the flange b b are of smaller diameter thanthe neck of the bottle in which they are to be used, and the ring c isot' suchv size as to clasp the conical body with suicient force toretain its position on the stopper when not inserted in the jar, and ofsuch thickness that its external diameter is considerably greater thanthat of the mouth ofthe jar, so that, when inserted, it is so compressedas to flatten and extend it so as tocover the whole or a greater' partof the conical parta, and also compress it closely intd the anglebetween said partand the abrupt shoulder of the an ge b.

pering, being largest at the mouth.. rlhis form facilitates theinsertion ot'my improved stopper, but is not essential, as it litsequally tight if the neck is not ta- Y pering, after sutlicient forcehas been used to drive it The action of pushing, the stopper in firstcompresses the ring against the shoulder b, when its elasticity causesit to extend downward in the narrowing interstice, until an equilibriumexists between the two extremities, which correspond in form and actionto a wedge, the lower being the point and the upper the head, driven inand held by the flange or shoulder b.

1t is withdrawn with comparative ease, on account of the cylindricalform ofthe packing-ring, which rolls 'as the stopper comes out, and may,it the resistance is great, 'be disconnected from it, the `parts in suchease being separately removed, and the ring again placed on the stopperfor subsequent use.

The stopper is capable of repeated service, the use not being injuriousto it in any manner, and it is designed to be manufactured and soldseparately from the jars, of assorted sizes adapted to the usual rangeof diiierent-sized bottles, its construction being such as 'to insure asuitable t of the same stopper with considerable variation in the sizeofthe neck of the bottles.

I'claim as my invention- An improved bottle-stopper, formed of theconicalshouldered stopper or plug A and cylindrical packingging c,constructed and operating substantially as set orth. v

Inwitncss whereof I have hereunto signed myrname in the prescnceof twosubscribing witnesses.
